Answer:
Step-by-step explanation:
Study the steps used to solve the equation.
Given: StartFraction c Over 2 EndFraction minus 5 equals 7
Step 1: StartFraction c Over 2 EndFraction minus 5 plus 5 equals 7 plus 5
Step 2: StartFraction c Over 2 EndFraction plus 0 equals 12
Step 3: StartFraction c Over 2 EndFraction equals 12
Step 4: 2 (StartFraction c Over 2 EndFraction) equals 12 (2)
Step 5: c equals 24
Step-by-step explanation:
cost per day
= $1500 / week
= $1500 / 7 days
= $1500 ÷ 7 / 7 ÷ 7
≈ $214,29 / day

How many times does 8 go into 285?
Answer:
The time now is 7 pm
Step-by-step explanation:
Suppose that now is the time T.
We know that:
"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".
Then:
if we define midnight as 12, and we assume that T is in the pm range.
Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))
With this in mind, we can write the problem as:
12 - (T + 4) = (1/4)*( 12 - (T + 1))
Now we can solve this for T.
12 - T - 4 = (1/4)*(12 - T - 1)
8 - T = (1/4)*(11 - T)
4*(8 - T) = 11 - T
32 - 4*T = 11 - T
32 - 11 = -T + 4*T
21 = 3*T
21/3 = T
7 = T
Then T = 7 pm
The time now is 7 pm
